The maximum permitted phase error
must be defined, before t
defined using the following formula:
Using this calculated value in Fig.32,
it is possible to define the value of
C
36 and f
and using Fig.32, it can be seen that
C
With the addition of one retriggerable
monostable (e.g. “123”, “423” or
“4538”) a steady state LOW and
HIGH indication can be obtained, as
shown in Fig.33.
